What you are looking for is a common factor of v1 and v2 ie a number which
goes into both. A human brain would do this intuitively, but what you need to
do depends on the outcome required ie do you want the HIGHEST common factor,
the LOWEST or just any old one ? Would you prefer an integer or not ?

If you want an integer then find the factors of each, compare them, and choose
the most useful number that appears in both lists.

--Prog to find factors

sequence factors
atom v,res

for a=1 to floor(v/2) do
  res=v mod a    -- find remainder, syntax may be incorrect
  if res=0 then
    factors=factors&res
  end if
next
